I have been taking Phenterrmine for 3 months and after needing to up the dosage have been loosing 1-2 pounds per week. I have 2 months left of the prescription and am very happy with how I feel. More energy, reduced appetite, better will power. I have 80 more pounds that I want to lose and am very worried about what to do when the prescription runs out. My doctor has suggested switching to another weight loss drug, possibly Qysmia Belviq, or Saxenda. Wondering what others have done. I have worked so hard and want to keep the weight off and not gain it back.
